  • Island Hopping Strategy

    The crossing of an ocean by a series of shorter journeys between islands, as opposed to a single journey directly to the destination. In military strategy, it is the method of conquering islands in a steady sequence, usually with a defined endpoint.

    Six months after the attack on Pearl Harbor, the United States defeated Japan in one of the most decisive naval battles of World War II. Thanks in part to major advances in code breaking, the United States was able to preempt and counter Japan’s planned ambush of its few remaining aircraft carriers, inflicting permanent damage on the Japanese Navy.

    This World War II clash followed the Allied landing at the Philippine island of Leyte in October 1944. The Japanese sought to converge three naval forces on Leyte Gulf, and successfully diverted the U.S. Third Fleet with a decoy. At the Suriago Strait, the U.S. Seventh Fleet destroyed one of the Japanese forces and forced a second one to withdraw. The third successfully traversed the San Bernadino Straight but also withdrew before attacking the Allied forces at Leyte.
  • battle of Iwo Jima

Iwo Jima was defended by roughly 23,000 Japanese army and navy troops, who fought from an elaborate network of caves, dugouts, tunnels and underground installations.
